AR3011 Technology Overview
The Atheros AR3011 is a highly integrated, all-CMOS, single chip Bluetooth 2.1 + EDR solution specifically designed for PC applications. It includes a Bluetooth EDR radio, a 32-bit Tensilica CPU, USB 2.0 interface, two 1.2v voltage regulators for analog and digital circuit, auxiliary serial Flash interface, on board PLL, and on board RAM/ROM. It also has a WLAN coexistence interface to ensure coexistence and co-location with a WLAN solution in the same system.
The Atheros AR3011 supports the standard HCI USB interface which makes it compatible with any upper layer Bluetooth stack. It is specially optimized for PC applications and, as a result, eliminates the need for an external Flash, which further reduces the external component count and lowers system BOM cost.* The Atheros AR3011 can provide PC ODMs/OEMs with the lowest-cost Bluetooth solution.
